Abstract (en)

[origin: EP3968628A1] A projection system includes an imaging unit, a projection unit, and a controller. The imaging unit captures an image of a subject to generate a first captured image. The projection unit projects a projection image corresponding to the first captured image onto the subject. The controller has a first operation mode and a second operation mode, the first operation mode being a mode to generate the projection image corresponding to the first captured image and to cause the projection unit to project the projection image, and the second operation mode being a mode to adjust a positional relationship that brings a position in the first captured image and a position in the projection image into correspondence with each other. In the second operation mode, the controller causes the projection unit to project a marker image including a marker indicating a reference in the positional relationship, acquires a second captured image generated by the imaging unit capturing an image of the projected marker image, and adjusts the positional relationship, based on the marker in the marker image and the marker in the second captured image.
